Product details
Overview
74LV541D,118 from NXP Semiconductors is an octal non-inverting 3-state buffer/line driver in SO20 package, operating from 1.0 V to 3.6 V supply, with dual active-low output enable inputs (OE1, OE2), −40 °C to +125 °C temperature range, and TTL-level input compatibility at VCC ≥ 2.7 V. It serves as a level-shifting bus interface in low-voltage microcontroller peripheral expansion systems.
For engineers reviewing the 74LV541D,118 datasheet, 74LV541D,118 pinout, 74LV541D,118 application, or 74LV541D,118 equivalent, key selection criteria include supply voltage flexibility (1.0–3.6 V), guaranteed 3-state timing (enable/disable < 45 ns at 3.3 V), output drive capability (±8 mA), industrial temperature rating, and SO20 footprint compatibility with legacy 74HC/HCT logic families.
Technical Context
The 74LV541D,118 implements eight independent non-inverting buffer channels, each with high-impedance (Z) output control via two shared active-low enables. Its Si-gate CMOS architecture ensures low static current (≤160 µA at 3.6 V) and robust noise immunity, with input thresholds defined for TTL compatibility only when VCC is 2.7 V or higher.
Functional behavior follows a strict truth table: outputs Y0–Y7 are driven HIGH/LOW only when both OE1 and OE2 are LOW; any HIGH on either enable forces all outputs into high-impedance state. Propagation delay (An→Yn) is 10 ns typical at 3.3 V/15 pF, while enable/disable times are 19 ns and 21 ns typical under identical conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.0 V to 3.6 V - supports direct interfacing with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive, industrial PLC, and extended-range embedded applications. |
| Output Drive | ±8 mA at VCC = 3.0 V - sufficient to drive standard 50 pF loads across PCB traces or multiple CMOS inputs. |
| Propagation Delay | 10 ns typical (VCC = 3.3 V, CL = 15 pF) - enables reliable operation in 50 MHz bus systems with margin. |
| Enable/Disable Time | 19 ns / 21 ns typical (VCC = 3.3 V) - ensures clean bus arbitration and avoids output contention during state transitions. |
| Input Thresholds | VIL ≤ 0.8 V, VIH ≥ 2.0 V (VCC = 2.7–3.6 V) - guarantees TTL-compatible recognition of 0.8 V/2.0 V logic levels. |
| ESD Protection | HBM > 2000 V, MM > 200 V - meets IEC61000-4-2 Level 2 requirements for board-level handling robustness. |
Pinout & Package
74LV541D,118 is housed in a plastic small outline package (SO20, SOT163-1) with 20 leads, 7.5 mm body width, and 1.27 mm lead pitch. The package is RoHS-compliant and rated for reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE1) | Active-low output enable | Drives all Y0–Y7 outputs to high-impedance when HIGH; must be LOW with OE2 for functional output. |
| 2–9 (A0–A7) | Data inputs | Non-inverting inputs accepting 1.0–3.6 V logic; TTL-compatible only above 2.7 V supply. |
| 10 (GND) | Ground reference | Primary 0 V return path for all internal circuitry and output current sinking. |
| 11–18 (Y0–Y7) | 3-state buffered outputs | Drive HIGH/LOW when both OEs are LOW; enter high-Z when either OE is HIGH. |
| 19 (OE2) | Active-low output enable | Second enable input - both OE1 and OE2 must be LOW for output assertion. |
| 20 (VCC) | Power supply | Single positive supply rail (1.0–3.6 V); decoupling capacitor required near pin for noise suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Low-voltage operation | Functions down to 1.0 V supply - enables direct use with ultra-low-power MCUs and battery-backed systems. |
| TTL input compatibility | Valid VIH/VIL thresholds at VCC ≥ 2.7 V - allows seamless replacement of 74HCT541 in mixed-voltage designs. |
| Output ground bounce control | Typical < 0.8 V at VCC = 3.3 V - reduces switching noise coupling into analog sections or sensitive clock domains. |
| High-impedance output undershoot | VOH undershoot > 2 V at VCC = 3.3 V - prevents false triggering of downstream receivers during enable transitions. |
| Extended temperature range | Specified from −40 °C to +125 °C - eliminates derating concerns in thermally demanding enclosures or engine compartments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal non-inverting 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC541APW,118 | Lower ICC (max 10 µA vs. 70 mA), wider VCC range (1.2–5.5 V), but only rated to +85 °C. | Suitable for commercial-grade portable electronics; not qualified for automotive or extended-temperature industrial use. | Select when power budget is critical and temperature range ≤ +85 °C suffices. |
| SN74LV541ADW | Same electrical specs and SO20 package, but TI's version has different thermal derating (8 mW/K above 70 °C) and slightly tighter VOH/VOL min/max bounds. | Drop-in compatible in layout and function; minor parametric differences require validation only for worst-case timing analysis. | Choose for dual-sourcing where TI's supply chain or qualification documentation is preferred. |
Compared with 74LVC541APW,118, the 74LV541D,118 provides guaranteed +125 °C operation and higher drive strength, while SN74LV541ADW offers identical functionality with alternate sourcing-making 74LV541D,118 optimal for thermally demanding, high-reliability systems requiring NXP's long-term industrial support.

FAQ
What is the minimum supply voltage required for functional operation of the 74LV541D,118?
The 74LV541D,118 is guaranteed to operate down to 1.0 V supply voltage, with full static and dynamic specifications met across the 1.0 V to 3.6 V range. At 1.0 V, input levels are interpreted as GND or VCC only; TTL compatibility requires VCC ≥ 2.7 V. This makes the 74LV541D,118 suitable for battery-powered systems where supply droop occurs.
Can the 74LV541D,118 replace a 74HC541 in an existing design?
Yes, the 74LV541D,118 is pin and function compatible with 74HC541 and 74HCT541, but operates at lower voltages (1.0–3.6 V vs. 2.0–6.0 V). When replacing 74HC541 in a 3.3 V system, verify that input transition rates comply with ∆t/∆V limits (≤100 ns/V at 3.3 V) and that load capacitance remains ≤50 pF. The 74LV541D,118 retains identical pinout and logic behavior.
What is the maximum capacitive load the 74LV541D,118 can drive while maintaining specified timing?
The 74LV541D,118 propagation delay and enable/disable times are characterized with CL = 15 pF (typical) and CL = 50 pF (limiting). For guaranteed 10 ns typical tpd at 3.3 V, keep total load ≤15 pF. Up to 50 pF is supported with increased delay (≤23 ns max at 3.3 V), provided output current stays within ±8 mA limits. Exceeding 50 pF risks timing violations and signal integrity loss.
How does the dual output enable (OE1 and OE2) function in the 74LV541D,118?
In the 74LV541D,118, both OE1 (pin 1) and OE2 (pin 19) are active-low enables. All eight outputs (Y0–Y7) are driven only when both OE1 and OE2 are LOW. If either OE is HIGH, all outputs enter high-impedance state regardless of input states. This dual-enable structure allows coordinated bus control with redundancy or split enable logic in complex systems.
Is the 74LV541D,118 suitable for automotive applications requiring AEC-Q100 qualification?
The 74LV541D,118 is not AEC-Q100 qualified. While it is specified from −40 °C to +125 °C and used in automotive subsystems like body control modules, NXP does not list it under its AEC-Q100 product portfolio. For AEC-Q100-compliant alternatives, consider NXP's automotive-grade logic families such as the 74AUP series, or consult NXP's official automotive qualification documentation for the 74LV541D,118.
